Abstract

La présente invention concerne un récipient de traitement (1) qui est formé par la superposition d'un boîtier de filtre (2), d'un boîtier de pulvérisation (3), d'un récipient de matière première (4) et d'une unité d'alimentation en air (5), entre lesquels l'étanchéité à l'air est assurée par des dispositifs de jonction étanches à l'air (61-63). Dans le dispositif de jonction étanche à l'air (61), deux parties de joint (91, 92) sont prévues dans la direction radiale, et des joints en U (64, 65) sont installés. Les joints en U (64, 65) se déplacent verticalement dans des rainures de joint (67, 68) par une alimentation en air dans ou une évacuation d'air de chambres cylindriques (69, 71) pour obtenir de cette manière un contact étroit avec ou un détachement du rebord (74). Pendant le traitement des particules, l'étanchéité à l'air de la partie de joint (91) est maintenue par le joint en U (64). Pendant le refroidissement du récipient de traitement, l'étanchéité à l'air de la partie de joint (92) est maintenue par le joint en U (65) pour empêcher de cette manière une exposition de celle-ci. Simultanément, le joint en U (64) est élevé pour obtenir de cette manière un nettoyage de la partie de joint (91) au niveau du traitement des particules.
